Produced by Zhongtian HengyuanPAC, PAM dry powder feeding deviceHigh quality and affordable prices, with comprehensive after-sales service, have been well received by a large number of domestic users and friends.

Firstly, the automatic water supply system of PAC and PAM dry powder feeding devices

Composed of ultrasonic level gauge, solenoid valve, electromagnetic flowmeter, and pipeline. When the ultrasonic level gauge detects a low liquid level, it sends a signal to the control system PLC. The control system receives the signal and automatically calculates the required ratio concentration based on the existing solution concentration and the pre-set ratio concentration. According to the concentration ratio, it automatically opens and adjusts the solenoid valve flow rate and feeding system feeding amount.

Ultrasonic level gauge effectively and accurately controls the liquid level. Nowadays, in order to save costs in the market, most of them use float ball level control. Float ball level control has the advantage of low cost, but the disadvantage is that when the particle content of the medicine liquid is high or viscous, the float ball will be immersed in such liquid for a long time, which will directly affect the sensitivity of the float ball to float up and down. In severe cases, the float ball will completely lose its ability to float up and down, thereby affecting the effective control of the liquid level, affecting the concentration ratio or losing the ability of automatic control, causing the dissolution tank to overflow at any time, resulting in losses. The dry powder dosing device designed, developed and produced by Chengdu Chuangying Environmental Protection Equipment Co., Ltd. adopts a stable ultrasonic level gauge in the liquid level control monitoring part, which can monitor the liquid level height in real time online. This means that the control system PLC can collect liquid level height data in real time, issue commands in real time, and ensure the stable operation of the water supply system. At the same time, the ultrasonic level gauge can set multiple alarm points.

Electromagnetic flow meters can collect real-time pipeline flow and calculate monthly, quarterly, annual, and total flow rates. The main electromagnetic flowmeter can output a 4-20mA signal to the control system PLC. The PLC receives the flow signal and compares it with the required flow rate to calculate it. The PLC automatically adjusts the opening flow rate of the electromagnetic valve to achieve precise water supply function. The dry powder dosing system can read the monthly flow rate, quarterly flow rate, annual flow rate, and total flow rate of the electromagnetic flowmeter, in order to obtain the previous liquid preparation and dosing amount of this equipment, and thus grasp the past usage situation.

Secondly, the automatic mixing system of PAC and PAM dry powder feeding devices

The automatic blending system mainly consists of three tanks, three dissolution mixers, and a pre mixer. The feeding system screw inputs the dry powder into the pre mixer for thorough mixing, and then injects it into the solution tank for stirring. This ensures that the input dry powder does not clump or agglomerate in the tank, allowing it to fully dissolve into the dissolution tank without causing waste. The dissolving mixer and the continuous mixer in the dissolving tank ensure that the dry powder is fully dissolved, and the dissolved liquid enters the next stage of the maturation process. The mixer in the maturation tank continuously stirs and matures, and the matured solution is stored in the third tank storage tank, waiting for the use of the dosing system.

Thirdly, the automatic dosing system

The automatic dosing system mainly consists of metering pumps, safety valves, back pressure valves, buffers, etc. The control system in the dry powder dosing system automatically collects the sewage treatment amount through sensors and adjusts the dosing amount of the dosing system in real time (i.e. adjusts the flow rate of the metering pump). Among them, safety valves, back pressure valves, and buffers can make the dosing system operate more safely and stably.

Fourthly, the automatic control system PLC

The automatic control system mainly consists of Siemens PLC, touch screen (optional) and its electrical components. (Remote network connection and remote monitoring can be implemented according to user needs). There are two ways to control: manual control and automatic control. Real time liquid level height, configured solution concentration, configured solution volume, inlet flow rate, feeding amount, hopper material quantity, dosing metering pump flow rate and other parameters can be transmitted to the upper computer. Through remote control, equipment operation can be started and stopped, and the feeding water volume and feeding amount can be adjusted remotely. Realize true remote monitoring and control. The dry powder feeding system achieves unmanned intervention in the entire process of water inlet, feeding, dilution, maturation, drug storage, and drug addition, realizing remote automation control and greatly reducing the cost of use.
